Aim: collect (reassembling from the “UDP puzzle”) data reading from the WR network and redistribute them to the proper DAQ elements. Data Queue. KM3NeT Phase 1 throughput. 26 DUs 18 DOMs per DU 31 3'' PMTs per DOM
Aim: collect (reassembling from the “UDP puzzle”) data reading from the WR network and redistribute them to the proper DAQ elements
Presence of the 40K and the DOM threshold set to 0.3 p.e.
Acoustic data throghput supposed to be ~ 1.5 Gbps
Number of STS
Fit the number of required DQs with the maximum buffering needed, due to possible network delays, and with the available RAM.
Seconds of acquisition
The UDP packet (datagram) can be at most the MTU = 1500B < sizeof(frame)
By the intrinsic nature of the UDP protocol we have that:
